Now that you've opened your MIDI in Anvil Studio, you'll want to make it sound 8Bit. To devamp your MIDI, listen to each track (you can listen to tracks individually by clicking the "On" column), and replace the current instrument with one of our "8Bit" instruments. Below is a list of the "8Bit" instruments that you can use. (They may sound cheesy in Windows but once imported in the ROM, they'll sound great.)

8 - Clav = "Buzzy 8Bit"
29 - Electric Guitar (Muted) = "Soft 8Bit"
81 - Lead 1 (Square) = "Bassy 8Bit"
88 - Lead 8 (Bass + Lead) = "Sharp 8Bit"
127 - Applause/Gunshot (?) = "Drums"
